Takashi Iwai 9ab0cb309e ALSA: Replace the word "slave" in vmaster API
Follow the recent inclusive terminology guidelines and replace the
word "slave" in vmaster API.  I chose the word "follower" at this time
since it seems fitting for the purpose.

Note that the word "master" is kept in API, since it refers rather to
audio master volume control.

Also, while we're at it, a typo in comments is corrected, too.
